In his Army photo, CPL Shayn Coleman is wearing a "chocolate chip cookie" uniform, which was worn by US Soldiers during Desert Shield/Desert Storm in 1990-1991. The uniform worn in Afghanistan in 2009 (when he lost his arm) looks entirely different.
On the APB Carter has out on Abby and Shayn, Shayn's eye color is listed as brown, yet the photo on the APB clearly shows he has blue eyes.
